It is a more far-fetched name for cainophobia ("fear of novelty and changes") that could be more adjusted to the "fear of exchange", since etymologically it would be a "phobia of metathesis", in the sense of "fear of transposition" that should be between two known objects or situations. The origin is Greek by 956; 949; 964; 945; ( Put "enter, in the midst of, after" ) 952; 949; 963; 953; 962; ( thesis "position, placement, presentation" ) 966; 959; 946; 959; 962; ( fovos "fear" ) .
